' A TTORNEX,

tional V-like slit H at each end to form in effect a pair of opposing lips, the lower edges 92 of which are tapered What I claim is:-

1. A tube closure comprising a threaded cap having a flanged opening in the top thereof, a

relatively thick rubber disc adapted to be placed within the said cap and adjacent to the said flanged opening, a slit like opening in the said rubber disc, the inner opposing edges of the slit like opening being tapered awayirom one another so as to form a valve like opening when raised.

2. A tube closure comprising a threaded shell, adapted to thread upon the neck of a collapsible tube, a flanged opening formed in the top of the said threaded shell, and adapted to retain a relatively thick rubber disc within the said shell between the flanged edges'oi the said opening and the top of the said neck of the collapsible tube, an opening cut in the said rubber disc, tapered lower opposing edges on the said rubber disc adjacent to the said opening and forming a part thereof, the tapered lower opposing edges enabling the contents of the collapsible tube to lift these tapered opposing edges and thus pro,- vide an opening for the emission of the tube contents.

3. A tube closure comprising a threaded shell, adapted to thread upon the neck of a collapsible tube, a flanged opening formed in the top of the said threaded shell, and adapted to retain a rubber disc within the said shell and between the said flanged opening and the top of the neck of the said collapsible tube, a slit like opening cut in the said rubber disc, secondary V-like slits cut at both ends of the said slit, so as to form lips, tapered lower opposing edges formed iii the said rubber disc adjacent to the said slit like opening and forming a part thereof, so as to form a valve disk, the tapered edges of the slit like opening permitting the said lips to open outwardly when the contents of the collapsible tube are forced against them.
